Upper chamber 101 is cleaned separately: for dishes requiring high frequency washing, the dishes may be placed in the upper chamber 101 by opening the door upward. Water flow enters the water softener from a water tap, the water softener flows into the base of the lower chamber 102, the second control valve 61 of the second water conveying pipe 6 of the lower chamber 102 is normally closed at the moment, a water path is blocked from flowing into the first spray arm of the lower chamber 102, the water pumping mechanism pumps water in the draining cavity of the lower chamber 102 into the first spray arm 2 of the upper chamber 101, and finally the water of the first spray arm 2 flows into the draining cavity 102 again after being sprayed out, so that the upper chamber 101 is cleaned independently in a circulating and reciprocating mode.

And simultaneously cleaning the upper chamber and the lower chamber: when a large amount of tableware needs to be cleaned at one time, the tableware can be placed in the cavity at the same time, and the cleaning efficiency can be improved due to the first spraying arm, the second spraying arm and the spraying piece. Water flow enters the water softener from the water faucet, the water softener flows into the lower cavity 102 again, the water level is higher than the impeller assembly 82 of the spraying piece 7 in the lower cavity 102 through the water level controller, the first control valve and the second control valve are both in an open state at the moment, the water pumping mechanism pumps water in the draining cavity 7 to the spraying piece 7 and the first spraying arm 2 and the second spraying arm 3, spraying is achieved, water flowing out through the spraying piece 7 and the first spraying arm 2 and the second spraying arm 3 finally flows into the draining cavity 1021, the whole cavity is cleaned simultaneously in a circulating reciprocating mode, a large number of tableware can be cleaned, and cleaning efficiency is improved.

The term "fluid communication" as used herein refers to a spatial relationship between two components or portions (hereinafter collectively referred to as a first portion and a second portion), i.e., a fluid (gas, liquid or a mixture of both) can flow along a flow path from the first portion or/and be transported to the second portion, and may be directly communicated between the first portion and the second portion, or indirectly communicated between the first portion and the second portion via at least one third member, which may be a fluid passage such as a pipe, a channel, a duct, a flow guide, a hole, a groove, or a chamber allowing the fluid to flow therethrough, or a combination thereof.
